JPH062159Y2 - Rotation indicator - Google Patents

Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a rotation amount indicator for use as an ink adjusting knob of an offset rotary preprinting device or an ink adjusting knob of an offset foam rotary press.

[Conventional technology]

This kind of rotation amount indicator rotatably supports a weight in a case, a scale plate is fixed to the weight, and a pointer is provided to rotate with respect to the weight as the case rotates.
Generally, a handle is fixedly mounted on the case.

[Problems to be solved by the invention]

When this kind of rotation amount indicator is attached to the ink adjustment knob of the offset rotary printing machine or the ink adjustment knob of the offset form rotary press to precisely set the rotation amount of the knob, the space between the mounting cores is, for example, 50 mm. Or install them at 40 mm intervals. However, there is no small-sized conventional rotation indicator that can be mounted in a narrow space between the mounting cores, and the conventional structure has a limit to miniaturization.

An object of the present invention is to provide a rotation amount indicator suitable for downsizing.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention has a cylindrical handle 2 which also serves as a case, a shaft body 6 axially projecting at a substantially central portion of the handle 2, and an eccentric portion of a plate-shaped flat plate portion. A weight 12 having a semi-tubular protrusion 12a rotatably supported by the shaft body 6 and protruding in a perpendicular direction to the lower portion thereof, a scale plate 14 fixed to the weight 12, and a protrusion provided above the weight 12. Second shaft body 16, a two-stage gear rotatably fitted in the shaft body 16, and a fixed gear 24 fixed to the shaft body 6 and meshing with one gear 20 of the two-stage gears. , The shaft 6
A gear 28 that is rotatably fitted in and meshes with the other gear 22 of the two-stage gear, and the scale plate 1 connected to the gear 28.
4 and a pointer 30 facing each other.

[Action]

The rotation of the handle 2 is transmitted to the pointer 30 via the gear 24, the gear 20, the gear 22, and the gear 28, and the rotation amount of the handle 2 interlocks with the weight 12 and the pointer 30 facing the scale plate 30. Directed by action. A structure in which the case and the handle are combined, a structure in which the gears 20 and 22 are rotatably supported on the upper part of the weight 12, and the lower part of the weight 12 is projected in a semi-tubular shape to increase the weight of the weight 12. With this structure, the whole structure can be made compact.

〔Example〕

Hereinafter, the configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.

Reference numeral 2 is a handle that also serves as a case and is made of a tubular member. A transparent cover plate 4 made of a glass plate is fitted and arranged on one side of the handle 2 and positioned by a ring. 6 is a handle 2 with a nut 8
Is a shaft body fixed to the inner vertical wall of the disk, and a disc-shaped weight 12 is mounted on the outer peripheral surface of the large diameter part of the shaft body via a ball bearing 10.
The eccentric part is rotatably fitted. A semi-cylindrical projection 12a is formed in the lower part of the weight 12, and the projection 1
A scale plate 14 is fixed to one end of 2a. A shaft body 16 is screwed and fixed to the upper portion of the weight 12 in a right angle direction, and a two-stage gear in which a large diameter gear 20 and a small diameter gear 22 are formed on the shaft body 16 via a spacer 18 is rotatably inserted. It is arranged. The large-diameter gear 20 meshes with a small gear 24 fixed to the small-diameter portion of the shaft body 6. The pinion gear 22
Engages with a large-diameter gear 28 rotatably fitted and arranged via a pipe 26 in a small-diameter portion of the shaft body 6. The pipe 26 is rotatably fitted into the shaft body 6 and fitted and fixed to the inner diameter portion of the large diameter gear 28, and a pointer 30 is attached to the tip of the pipe 26. The pointer 30 faces the scale of the scale plate 14. The gears 24, 2
Reference numerals 0, 22, and 28 constitute a speed reducing mechanism having a rotation ratio of 1/4.

In the above structure, the recessed portion of the handle 2 is inserted into the rotating member (not shown), and the fixing screw 32 is screwed in to fix the handle 2 to the rotating member. When the handle 2 is rotated, the small gear 24 rotates in conjunction with the handle 2,
The weight 12 is oriented toward the center of gravity and stands still. The large-diameter gear 20 is rotated by the rotation of the small gear 24, and the rotation is transmitted to the pointer 30 through the small gear 22, the large-diameter gear 28, and the pipe 26. The pointer 30 is interacted with the scale plate 14 by the interaction. The amount of rotation of the handle 2 is displayed.

〔effect〕

As described above, according to the present invention, the case and the handle are integrally formed, the gear is provided on the upper part of the weight, and the lower part of the weight is projected into the handle, so that the whole is compact without degrading accuracy. There are effects that can be configured into.
